Hi Stotzbotz, HowardR +
a lovely way to handle the Bonus-Countdown --- single bonus and double bonus. I had to mirror one part of the schematics to put the two parts together in my JPG.
StotzBotz - from Your description we know " The Score-Motor does turn while the Bonus is counted down. We also know that the Bonus-Score-Relay does pull (is actuated) at this time. If connecting wires are truely soldered-on (?) - switches truely close (or maybe the contact-points on the switch are oxidated) (?) we do not know.
See the JPG - good is "my rosa/pink stuff" - the stepping down of the bonus lights on the playfield because the Bonus-Unit-Reset-Coil is rhythmically made pulling (pull-in then let go). At exactly the same time there is another stepping (not functioning in Your pin) - rhythmically make pulling (pull-in then let go) along "my blue line (four times) , my brown line (one time)" synchronous stepping of Bonus-Unit-Reset-Coil and 1000-Point-Relay --- five times within the "turning of the Score-Motor turning half a revolution is 180 degrees". Everything "blue and brown" may be not working in Your pin. Greetings Rolf
